Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard technology, specifically a folding and pressing device for corrugated cardboard box production. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, consisting of at least one layer of corrugated core paper and one layer of cardboard. It possesses high mechanical strength, capable of withstanding impacts and drops during handling. After processes such as printing, die-cutting, creasing, and gluing, it is manufactured into corrugated boxes. It is precisely because of the high mechanical strength and impact and drop resistance of corrugated cardboard that corrugated boxes have become one of the most widely used packaging products.

[0003] When corrugated cardboard is folded, a crease is usually pressed into the surface of the cardboard by a folding plate to facilitate folding the corrugated cardboard into a carton. However, since different carton sizes require different sizes of corrugated cardboard, the folding spacing needs to be adjusted when making different sizes of cartons. Existing folding plates are not convenient for quickly adjusting the spacing between adjacent folding plates, thus affecting the folding efficiency of the corrugated cardboard. Therefore, we need to propose a folding device for corrugated carton production. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a folding and pressing device for corrugated cardboard box production, comprising:

[0023] The processing table 1 and the gantry 2 installed on the processing table 1 are provided. The gantry 2 is equipped with a main pressing mechanism 4. Multiple sets of auxiliary pressing mechanisms 5 are installed on the main pressing mechanism 4. Each set of auxiliary pressing mechanisms 5 is equipped with a folding plate 7 for folding corrugated cardboard at its lower end. The main pressing mechanism 4 enables the multiple sets of folding plates 7 to descend and fold synchronously.

[0024] Each auxiliary pressing mechanism 5 is equipped with a quick-locking structure 6. The auxiliary pressing mechanism 5 is secured to the main pressing mechanism 4 through the quick-locking structure 6 to achieve the pressing and folding of corrugated cardboard of different specifications.

[0025] The main pressure mechanism 4 includes a cylinder 41 installed on the top of the gantry 2. The telescopic end of the cylinder 41 passes through the gantry 2 and is fixedly connected to a base plate 42. Multiple sets of limiting rods 45 passing through the gantry 2 are fixedly connected to the upper surface of the base plate 42. The lower surface of the base plate 42 is provided with an installation groove 43 for multiple sets of auxiliary pressure mechanisms 5 to be installed, and two sets of guide rods 44 are provided in the installation groove 43.

[0026] In this embodiment, the cylinder 41 provides power to lift and lower the substrate 42, and the multiple sets of limit rods 45 ensure the stability of the lifting and lowering process of the substrate 42, avoiding deviation during the pressing and bending. At the same time, the mounting groove 43 and the guide rod 44 provide the mounting position and sliding guide for the multiple sets of auxiliary pressing mechanisms 5, ensuring the straightness of the auxiliary pressing mechanism 5 during adjustment.

[0027] The auxiliary pressure mechanism 5 includes a slide beam 51 that slides on two sets of guide rods 44. Two sets of telescopic sleeve rods 53 are fixedly connected to the lower surface of the slide beam 51. The lower ends of the two sets of telescopic sleeve rods 53 are fixedly connected to the upper surface of the pressure plate 7. A motor 55 is installed in the middle of the lower surface of the slide beam 51. The output shaft of the motor 55 is driven by a lead screw 56. The lower end of the lead screw 56 is threadedly connected to a screw cylinder 57. The screw cylinder 57 is fixedly connected to the middle of the upper surface of the pressure plate 7.

[0028] In a further preferred embodiment, the slide beam 51 can slide along the guide rod 44 to achieve position adjustment, adapting to the folding requirements of corrugated cardboard of different specifications. The telescopic sleeve 53 not only supports the folding plate 7, but also ensures its verticality when it is raised and lowered. Through the structure of the motor 55 driving the lead screw 56 and the screw cylinder 57, the height of the folding plate 7 can be precisely adjusted. Then, the height of the folding plate 7 can be adjusted according to the number of folds required for the corrugated cardboard, so that the number of folding plates 7 on the same horizontal plane is consistent with the number of creases required.

[0029] A toothed beam 46 is fixedly connected to one side of the base plate 42, and a scale groove is provided on one side of the toothed beam 46. An indicator head 54 for indicating the scale is fixedly connected to one side of the slide beam 51, and a groove for installing the quick-lock structure 6 is provided on the slide beam 51.

[0030] Preferably, the position parameters of each auxiliary pressure mechanism 5 can be read intuitively by indicating the scale groove through the indicator head 54, which facilitates the quick calibration of the spacing between multiple pressure plates 7 and improves the adjustment efficiency. The groove provides installation space for the quick-lock structure 6, so that the quick-lock structure 6 and the auxiliary pressure mechanism 5 form an integral whole and ensure the structural compactness.

[0031] The quick-lock structure 6 includes a pressure rod 61, a slider 62, and two sets of springs 64. Both sets of springs 64 are installed in the groove, and one end of each set of springs 64 is fixedly connected to the pressure rod 61 and the slider 62, respectively. The pressure rod 61 and the slider 62 are slidably inserted into the two ends of the groove, and the slider 62 is fixedly connected to the end of the pressure rod 61 located in the groove. The slider 62 is provided with multiple sets of teeth 63 that mesh with the toothed beam 46. A lever 52 is fixedly connected to one end of the lower surface of the slide beam 51.

[0032] In this embodiment, the quick-lock structure 6 provides elastic force through the spring member 64 (made of a return spring wrapped around the telescopic rod), so that the teeth 63 on the slider 62 are tightly engaged with the toothed beam 46, thereby achieving quick fixation of the position of the auxiliary pressure mechanism 5. The linkage design between the pressure rod 61 and the slider 62 means that the lock can be released simply by pressing the pressure rod 61, which is convenient to operate and greatly shortens the changeover time for corrugated cardboard pressing and folding operations of different specifications, thus improving production efficiency.

[0033] A connecting valve seat 9 is installed on one side of the processing table 1. A bottom cavity 10 communicating with the connecting valve seat 9 is opened inside the processing table 1. Multiple sets of air holes 11 communicating with the bottom cavity 10 are opened on the upper surface of the processing table 1. An anti-slip pad 12 is pasted on the upper surface of the processing table 1, and multiple sets of through holes communicating with the air holes 11 are opened on the anti-slip pad 12. A protruding beam 8 is fixedly connected to the upper surface of the processing table 1.

[0034] Specifically, the connecting valve seat 9 can be connected to an external negative pressure device. Through the bottom cavity 10 and the air hole 11, a negative pressure adsorption is formed. With the anti-slip pad 12, the corrugated cardboard can be firmly fixed on the processing table 1 to prevent the cardboard from shifting during the folding process. The protruding beam 8 can serve as a positioning reference during folding to ensure the straightness of the folding edge and improve product consistency.

[0035] A control panel 3 is installed on one side of the gantry frame 2, and a displacement sensor 13 for monitoring the distance between the pressure plate 7 and the slide beam 51 is installed on the lower surface of each set of slide beams 51.

[0036] Secondly, the displacement sensor 13 can monitor the distance between the folding plate 7 and the slide beam 51 in real time, ensuring that the folding plate 7 can be located on the same plane, which is convenient for timely adjustment and allows for easy adjustment of the position of the folding plate 7 according to the number of folds and indentations required for the corrugated cardboard.

[0037] When in use, the pressing and folding device first pushes the slide beam 51 along the guide rod 44 of the main pressing mechanism 4 according to the specifications of the corrugated cardboard to be processed by the lever 52. Combined with the scale groove of the toothed beam 46 and the indicator head 54, the position of each auxiliary pressing mechanism 5 is determined. Pressing the pressing rod 61 of the quick-lock structure 6 makes the teeth 63 of the slider 62 mesh with the toothed beam 46, thus fixing the position of the auxiliary pressing mechanism 5. Then, the corrugated cardboard is placed on the processing table 1 and contacts the protruding beam 8. Negative pressure is connected through the connecting valve seat 9. The negative pressure adsorption effect of the bottom cavity 10 and the air hole 11, combined with the anti-slip pad 12, fixes the cardboard.

[0038] Restart cylinder 41 to lower substrate 42, which in turn moves multiple sets of auxiliary pressing mechanisms 5 downwards simultaneously, causing multiple sets of folding plates 7 to fold the corrugated cardboard. After folding, cylinder 41 moves substrate 42 upwards to reset, the negative pressure is released, and the processed cardboard is removed, completing one folding operation.

[0039] When it is necessary to change the number of indentations, the motor 55 of the auxiliary pressing mechanism 5 drives the lead screw 56 to rotate, which facilitates the movement of the screw cylinder 57, thereby facilitating the raising of the corresponding folding plate 7, reducing the number of folding plates 7 used, and thus facilitating the pressing of corrugated cardboard when producing cartons of different specifications.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
